Diode power sensors range to 33 GHz, with USB and LAN connectivity

February 20, 2015 // By Graham Prophet
Rohde & Schwarz has added to its RF power sensor range of three-path diode sensors. In addition to its USB sensors, sensors that support LAN are now available, for remotely controlled applications over large distances.

R&S NRPxxS and R&S NRPxxSN USB three-path diode power sensors are completely redesigned sensors to offer enhanced measurement speed and measurement accuracy, even at low levels. The R&S NRPxxSN model offers both a USB and a LAN interface. Both power sensor models are available for three different frequency ranges, from 10 MHz to 8 GHz, to 18 GHz and to 33 GHz, the largest choice of ranges available.

NRPxxS/SN sensors enable 10,000 triggered measurements per second with a minimum trigger resolution of 100 µsec. A special mode permits in excess of 50,000 equidistant measurements per second. And the improved three-path diode design made it possible to decrease the lower measurement limit to -70 dBm. The result is a very wide dynamic range of 93 dB and instruments that can measure up to four times faster than previous solutions, especially at low levels.

The LAN interface on the R&S NRPxxSN model now allows remote power measurements over large distances. For example, it is possible to control monitoring applications for satellite systems or particle accelerators via a central PC by placing sensors at various positions in the system. The power sensor is controlled from a GUI accessed via web browser. No additional software is needed.

NRPxxS/SN power sensors help mobile communications users perform power measurements on signals such as GSM, 3GPP, LTE and LTE-Advanced. The 33 GHz model is also suitable for development and production of anticollision radar systems in the automotive sector. The continuous average, burst average, timeslot average, gate average and trace measurement test modes all remain available.
